AoE: ATA over Ethernet

Cover
AoE is a protocol that allows block access to very small, inexpensive servers called storage blades. By making the protocol light weight, the small servers can be very inexpensive so that users can have a lot of them. Each server has a single disk drive and constitutes a single blade in a small shelf of storage servers. This in combination with multiple inexpensive Open Source servers creates a powerful storage medium.

This paper describes the AoE protocol and how to use it. Familiarity with ATA and Ethernet are assumed, along with some knowledge of SAN and network storage. Developers who wish to use the protocol should consult the latest revision of the protocol spec.

In this article, the word server refers to network servers running systems such as Linux, FreeBSD, and Solaris. Blade refers to a storage blade running the AoE protocol. We have built a storage blade, and written a device driver. This paper include their performance measurements.
